The economic and environmental effect of energy saving measures were analyzed for a typical wheat production system in Germany. The introduction of precision farming, reduced nitrogen fertilization and improved crop drying technologies proved to be efficient measures for enhancing energy efficiency in wheat production. While the measures precision farming and improved crop drying require investments, reduced fertilizer input can be realized without investments. The environmental effects of all measures are comparable and do not show a clear advantage of one measure against the others. However, reduced fertilizer input implies an economic loss which is unlikely to be realized by farmers unless they are forced to do so.
